ATI Fundamentals

1. A healthcare professional is reviewing ABG laboratory results of a client who is in respiratory distress. The results are pH 7.47, PaCO2 32 mm Hg, and HCO3 22 mm Hg. The healthcare professional should recognize that the client is experiencing which of the following acid-base imbalances?

A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis
D. Metabolic alkalosis

Correct answer: B

Rationale: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.

2. What term refers to the manner of walking?

A. Gait
B. Range of motion
C. Flexion and extension
D. Hopping

Correct answer: A

Rationale: Gait specifically refers to the manner in which a person walks. It encompasses the pattern, rhythm, and style of walking, making it the most appropriate term in this context. Choices B, C, and D are incorrect. Range of motion refers to the extent of movement of a joint, flexion and extension relate to bending and straightening movements at a joint, and hopping is a specific type of movement that involves jumping on one foot.

3. When caring for a client in the advanced stage of amyotrophic lateral sclerosis (ALS), which of the following referrals is the nurse's priority?

A. Psychologist
B. Social worker
C. Occupational therapist
D. Speech-language pathologist

Correct answer: D

Rationale: In the advanced stage of ALS, speech and swallowing difficulties become significant. As a result, the priority referral for the nurse would be a speech-language pathologist. This professional can assist in managing communication challenges and provide strategies to address swallowing issues, ensuring the client's safety and quality of life.

4. When administering digoxin 0.125 mg PO to an adult client, for which of the following findings should the nurse report to the provider?

A. Potassium level 4.2 mEq/L.
B. Apical pulse 58/min
C. Digoxin level 1 ng/mL
D. Constipation for 2 days

Correct answer: C

Rationale: Monitoring the digoxin level is crucial as it helps determine the drug's effectiveness and potential toxicity. A digoxin level of 1 ng/mL is within the therapeutic range. However, levels above this range can lead to toxicity, causing adverse effects like nausea, vomiting, visual disturbances, and dysrhythmias. Therefore, the nurse should report a digoxin level of 1 ng/mL to the provider for further evaluation and potential dose adjustment.

5. What is the primary purpose of handwashing?

A. To promote hand circulation
B. To prevent the transfer of microorganisms
C. To avoid touching the client with a dirty hand
D. To provide comfort

Correct answer: B

Rationale: The primary purpose of handwashing is to prevent the transfer of microorganisms. Proper hand hygiene helps reduce the risk of spreading harmful bacteria and viruses, thus promoting overall health and preventing infections. Choice A is incorrect as handwashing primarily focuses on cleanliness rather than promoting circulation. Choice C is incorrect as it implies that the main concern is avoiding client discomfort rather than preventing infection. Choice D is incorrect as while handwashing can be comforting in some situations, its primary purpose is not to provide comfort but to maintain hygiene.
